Hard to explain. Are you familiar with an MTC slider clutch? Not even in the same zip code as what you did. Total respect here. Clutch pack is held open by weights and at a certain rpm determined by weights Let go of the 2step button a nd clutch pack gets instantly compacted a you launch. Then go through gear changes via air shifter. If you ride it back to the pits after a pass, you F up the clutch plates and you have nothing to read the pass by. Much like spark plugs. If you ride the bike back to the pits, spark plugs mean nothing. spark plug readings mean nothing.
Ok everyone

I thought that was a damn good explanation. I almost said as much but didn't. Now I am questioning my sanity again.
Reminds me of this ride. Old school blower, pushing only 8lbs on pump gas. I forget the man’s name but he does the machining of parts himself and is building another hemi with a blower for a 32 ford. Runs his belt super tight and it the whine is pretty awesome. He says it’s 700hp. I’ve never seen him get on it, not that that would tell me anything important. But it’s a neat ride. Kinda mad max.
That’s my buddy, Ron. He’s 6’-8” and was amazed at the room in the cab.

Of course not knowing all the pertinent details I wouldn’t swear to any numbers. However if thats 400 ci of anything just decent with 8lbs 700hp isnt hard to get.
Not my style of ride but I can certainly respect the work. Its definitely different.

OK, thank you, that helps. Now at least I can do some research to better understand. Drag racing on bikes is so completely different from road racing, but I like learning things, so now I can dig in and bug Google with some probably dumbass questions!
That what he was after, something different. It’s different. I usually pass him sideways hoping he will play along.. hasn’t taken the bait yet.Of course not knowing all the pertinent details I wouldn’t swear to any numbers.

My short block dyno’d 452 according to blueprint. I slapped the 8-71 on it at 10 lbs. no clue what I’m making.. I’m running 110 octane and 30* timing, just to be safe. If it’s over 600hp I’m happy.Of course not knowing all the pertinent details I wouldn’t swear to any numbers. However if thats 400 ci of anything just decent with 8lbs 700hp isnt hard to get.

Well the common theory is at around 15lbs you doubled your NA hp. Because you essentially doubled atmospheric pressure. Lets keep it simple 1/2 of that is 7.5 lbs boost. So 452hp plus 1/2 (226hp) = 678hp. That is at 7.5lbs boost and a very safe guess. There are variables like if you have a tiny blower or a poor design that is making excessive heat or the opposite having a state of the art intercooler with a proper sized blower. It all effects outcome but I see no reason you aren’t over 600hp
I’ve dicked around with Wallace racing calculators and came up with 717. That aluminum lung make a shit ton of heat though. I’m not a racer, just a burnout enthusiast.
